<p>本文记录学习《Spring实战》(第五版)中的知识点，并将一些开发项目中遇到的相关经验与理解记录在这里。</p>

<h2 id="第一部分-Spring基础">第一部分 Spring基础<a class="anchor" href="#第一部分-Spring基础">¶</a></h2>
<p>Spring的核心提供了一个叫做Spring上下文(Spring application context)的容器，其创建和管理应用组件(bean)。将bean组装在一起的行为是通过基于依赖注入(dependency injection,DI)的模式实现。组件不会创建它所依赖的组件并管理它们的生命周期，使用依赖注入的应用依赖于单独的实体（容器）来创建和维护所有的组件，并将其注入到它们所需的bean中。</p>
<p>以往，使用一个或多个xml文件指导Spring上下文将bean装配在一起。现在推荐使用基于java的配置。<code>@Configuration</code>注释告知Spring这是一个配置类，为Spring应用提供上下文。使用<code>@Bean</code>注释标注，表明方法返回的对象会以bean的形式添加到Spring的上下文。(默认这些bean对应的bean ID与定义它们的方法名称相同)。</p>
<p>基于java的配置相较于xml有更强的类型安全性和更好的重构能力。</p>
<p><strong>只有当Spring不能进行自动配置时，才需要显示配置。</strong></p>

<p>Spring Initializr是一个能够生成Spring Boot项目的REST API。</p>
<p>Spring项目的目录结构：</p>
<ul>
<li>mvnw和mvnw.cmd：Maven包装器(wrapper)脚本。即使机器上没有安装Maven，也能构建项目。</li>
<li>pom.xml：Maven构建规范。</li>
<li>application.properties：最初该文件是空的，为我们提供制定配置属性的地方。</li>
<li>resources/static：存放任意为浏览器提供服务的静态内容。</li>
<li>resources/templates：存放用来渲染内容到浏览器的模板文件。</li>
</ul>
<p>Spring Boot starter依赖它们本身不包含库代码，而是传递性的拉取其他的库。这样做的好处如下：</p>
<ul>
<li>构建文件会显著减小并易于管理。不必为每个所需的依赖库都声明依赖。</li>
<li>能够根据它们所提供的功能来思考依赖，而不是库名称。</li>
<li>不必担心库版本问题。可以相信给定版本的Spring Boot，传递性引入的库的版本是兼容的。只要关心Spring Boot版本就行。</li>
</ul>
<p>Spring Boot maven plugin：1.提供一个maven goal，允许我们使用maven来运行应用。2.确保依赖的所有库都包含在可执行的jar文件中，并保证它们在运行时类路径下可用。3.它会在jar中生成一个manifest文件，将引导类声明为可执行jar主类。</p>
<p><code>@SpringBootApplication</code>是一个组合注释，如下：</p>
<ol>
<li><code>@SpringBootConfiguration</code>：将该类声明为配置类。实际上该注释是<code>@Configuration</code>的特殊形式。</li>
<li><code>@EnableAutoConfiguration</code>：启用Spring Boot的自动配置。</li>
<li><code>@ComponentScan</code>：启用组件扫描。</li>
</ol>
<p>测试类带有<code>@RunWith(SpringRunner.class)</code>注解。其是Junit的注解，它会运行一个测试运行器(runner)来指导JUnit如何运行测试。本例子中为JUnit提供的是SpringRunner，这个是一个Spring提供的测试运行器，它会创建测试运行所需的Spring应用上下文。<code>@SpringBootTest</code>告诉JUit在启动测试时添加上Spring Boot功能</p>
<p>SpringRunner是SpringJUit4ClassRunner的别名，于Spring4.3引入，移除了对特定JUit版本的关联。</p>
<p>Spring自带一个强大的Web框架，Spring MVC。其核心是控制器的理念(处理请求并以某种方式进行信息响应的类)。</p>
<p>在Spring Boot2.2之后，默认的测试工具变成了Junit5。有两种方法进行测试:1.直接写<code>@SpringBootTest</code>，如果测试MVC加上注释<code>@AutoConfigureMockMvc</code>，注入一个<code>Autowired</code>的<code>MockMvc</code>对象。2.声明<code>@ExtendWith(SpringExtension.class)</code>替换<code>@RunWith(SpringRunner.class)</code>。设置<code>@WebMvcTest(所需测试的Controller.class)</code>。</p>

<p><code>@RequestMapping</code>：注释到类级别的时候，它能够指定该控制器所处理的请求类型。</p>
<p>在方法上的<code>@GetMapping</code>注释对类级别的<code>@RequestMapping</code>细化。<code>GetMapping</code>是Spring4.3引入，之前的是<code>@RequestMapping(method=RequestMethod.GET)</code>。</p>
<table>

<p>在为控制器方法声明请求映射时，越具体越好。意味着至少要声明路径(或者从类级别的QRequestMapping继承一个路径)以及它所处理的HTTP方法。<strong>推荐在类级别上使用@RequestMapping以便于指定基本的路径。在每个处理器方法上，使用更具体的@GetMapping或@PostMapping注解。</strong></p>
<p>DevTools是Spring开发人员的开发期工具，包括：</p>
<ul>
<li>代码变更后应用自动重启。</li>
<li>当面向浏览器的资源（如模板、Js、样式表）等发生变化时，会自动刷新浏览器。</li>
<li>自动禁用模板缓存。</li>
<li>如果使用了H2数据库，内置H2控制台。</li>
</ul>
<p>当DevTools运行时，应用程序会被加载到Java虚拟机两个独立的类加载器中。其中一个类加载器会加载Jva代码、属性文件和项目中"src/main"路径下几乎所有的内容。另一个类加载器会加载依赖的库。当检测到变更时，DevTools只会重新加载包含项目代码的类加载器，并重启应用上下文。另一个类加载器和jvm保持不变，缩短应用启动时间。但<strong>导致自动重启无法反映依赖项的变化。需手动重新启动应用</strong>。DevTools在应用程序运行时，自启动一个LiveReload服务器。当LiveReload服务器与LiveReload浏览器插件结合时，有变化时自动刷新浏览器。</p>
<p><strong>推荐使用Idea中的插件JRBEL</strong></p>

<p>Q :为什么只有一个整体的@EqualsAndHashCode注解，而不是分开的两个@Equals和@HashCode？</p>
<p>A : 在Java 中有规定，当两个object equals 时，他们的hashcode 一定要相同，反之，当hashcode 相同时，object 不一定equals。所以equals 和hashcode 要一起implement，免得发生违反Java 规定的情形发生</p>

<p>这里注意一个Java 的小坑，当我们没有指定constructor 时，Java compiler 会帮我们自动生成一个没有任何参数的constructor 给该类，但是如果我们自己写了constructor 之后，Java 就不会自动帮我们补上那个无参数的constructor 了</p>
<p>然而很多地方（像是Spring Data JPA），会需要每个类都一定要有一个无参数的constructor，所以<strong>你在加上@AllArgsConstructor时，拜托，一定要补上@NoArgsConstrcutor，不然会有各种坑等着你</strong></p>

<p>@RequiredArgsConstructor：生成一个包含“特定参数”的constructor，特定参数指的是那些有加上final修饰词的变量们</p>

<p>如果所有的变量都是正常的，都没有用final 修饰的话，那就会生成一个没有参数的constructor。</p>
</li>
<li>
<p>@Value 基本与@Data相同，不同在于它会把所有变量设置为final。相应的也就没有setter方法了。</p>

<p>此lombok 的注解@Value 和另一个Spring 的注解@Value 撞名，在import 时不要import 错了。</p>
</li>
<li>
<p>@Builder，自动生成流式set 值写法，从此之后再也不用写一堆setter 了</p>
<p><img src="https://cdn.jsdelivr.net/gh/weiyouwozuiku/weiyouwozuiku.github.io@src/source/_posts/%E7%A8%8B%E5%BA%8F%E8%AE%BE%E8%AE%A1/Java/Spring%E5%AE%9E%E6%88%98%E5%AD%A6%E4%B9%A0/lombok_builder.png" alt="lombok_builder.png"></p>
<p>注意，虽然只要加上@Builder 注解，我们就能够用流式写法快速设定Object 的值，但是setter 还是必须要写不能省略的，因为Spring 或是其他框架有很多地方都会用到Object 的getter/setter对他们取值/赋值。所以<strong>通常是@Data 和@Builder 会一起用在同个类上，既方便我们流式写code，也方便框架做事</strong>。</p>

<h4 id="RequestMapping">@RequestMapping<a class="anchor" href="#RequestMapping">¶</a></h4>
<p>只是简单的使用@RequestMapping注解表示这个接口支持所有的请求方式</p>
<h4 id="GetMapping">@GetMapping<a class="anchor" href="#GetMapping">¶</a></h4>
<p>不同于上一个@RequestMapping，其表示只接受get请求方式。或者写成<code>@RequestMapping(value="/hello", method=RequestMethod.GET)</code>，效果一样。</p>
<h4 id="ComponentScan">@ComponentScan<a class="anchor" href="#ComponentScan">¶</a></h4>
<p>该注解实现了扫描包的功能。但是<strong>其只会扫描当前文件夹及其子文件夹的内容，对于上级或同级目录不会扫描。</strong></p>
<p>使用时在需要添加扫描的类上加上这个注解，并在注解后面的括号中写上包名，如<code>@ComponentScan("com.wangzhengbest.wiki")</code>。**不要只写com,会扫描到第三方Jar,出错非常难排查。**使用<code>@ComponentScan({"com.wangzhengbest","top.buerlog"})</code>扫描多个包。</p>
<h4 id="Value">@Value<a class="anchor" href="#Value">¶</a></h4>
<p>该注解可以将配置文件中的变量读取到程序中。例如<code>@Value("${test.hello:Test}")</code>就会去读取配置文件中的test.hello字段。后面的<code>:Test</code>表示这个值没有在配置文件中读取到时赋值为Test。</p>
<h3 id="测试">测试<a class="anchor" href="#测试">¶</a></h3>

<p>mapper层设置完毕之后，还不能被spring扫描到。因此需要在启动spring的<code>XXXApplication.java</code>文件中添加上注解<code>@MapperScan("com.wangzhengbest.WIKI.mapper")</code>。这里的包路径就是mapper层的路径。</p>
<p>同理，sql对应的xml文件建立后，需要在<code>application.properties</code>文件中添加：</p>
<pre class="line-numbers language-markup" data-language="markup"><code class="language-markup">#配置mybatis所有Mapper.xml所在的路径
mybatis.mapper-locations=classpath:/mapper/**/*.xml<span aria-hidden="true" class="line-numbers-rows"><span></span><span></span></span></code></pre>
